Answer Posted / Hari Narayan Dwivedi
For a feedback circuit to produce sustained oscillations, it must meet certain conditions: 1) The gain (amplification factor) of the amplifier should be greater than one. 2) The phase shift introduced by all components in the feedback path should be approximately zero or 360 degrees. 3) The loop gain should exceed -1.

Keep this in mind and try to complete the sequence with the appropriate number: 201315, 71280, 9253, 212, ?
